Spatial Coupling in Turbo Equalization

In this paper we consider spatial coupling in turbo equalization and demonstrate that the code design trade-off between the performance in waterfall and error floor regions can be avoided. We introduce three coupling schemes and compare their performances, where the first method introduces coupling between the encoder and the channel, while the second uses a spatially coupled (SC) code. In the thi

On the Complexity Requirements of a Panel-Based Large Intelligent Surface

A Large Intelligent Surface (LIS) is a recently proposed concept, especially suitable for high speed indoor communications and industrial internet of things (IoT) applications. Basing the LIS on smaller panels has clear advantages in terms of flexibility and mass production of its elements. In this paper we consider a panel-based LIS and we study the interplay of the panel size, the number of base

Acoustic design of ordinary rooms using absorbers and diffusers

With different activities in a room, room acoustic requirements differ and when the acoustic requirements are different, acoustic treatment must be adapted. This study focuses on room acoustics in ordinary public rooms such as classrooms and offices. By tradition the acoustic treatment in these rooms is an absorbent ceiling. Experiments have been carried out in a classroom where the baseline in th

Epsilon waves as an extreme form of depolarization delay : Focusing on the arrhythmogenic right ventricular cardiomyopathy/dysplasia

Revision of the Task Force diagnostic criteria (TFC) for arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D), in 2010, has increased the sensitivity for the diagnosis of early and familial forms of the disease. Epsilon wave (EW) is a major diagnostic criterion in the context of ARVC/D, however, it remains unquantifiable and therefore, may leave room for substan-tial subjective inter

Effects of Sex on Early Outcome following Repair of Acute Type A Aortic Dissection : Results from the Nordic Consortium for Acute Type A Aortic Dissection (NORCAAD)

Background Female sex is known to have increased perioperative mortality in cardiac surgery. Studies reporting effects of sex on outcome following surgical repair for acute Type A aortic dissection (ATAAD) have been limited by small cohorts of heterogeneous patient populations and have shown diverging results. This study aimed to compare perioperative characteristics, operative management, and pos

Mayr Versus Woese : Akaryotes and Eukaryotes

In 1998, on the brink of a great public effort that by now has delivered the sequences of thousands of genomes and has annotated these genomes by translating tens of thousands of 3D protein domain structures from their coding sequences, Ernst Mayr and Carl Woese engaged in a debate. At issue were the virtues of phenotypic contra genotypic approaches to phylogeny and taxonomy. Though not conclusive

Applying the ecosystem model in a new context? The case of business incubation in Oman

This paper studies entrepreneurship ecosystem development in a context little discussed in the extant literature to date: Oman. Specifically, it focuses on business incubation (BI) initiatives as a policy tool for developing the local, regional, and national systems of supporting entrepreneurship and SME growth. Although BI’s are a popular policy measure for ecosystem development, spreading global

Proteins linked to atherosclerosis and cell proliferation are associated with the shrunken pore syndrome in heart failure patients

PURPOSE: The "Shrunken pore syndrome" (SPS) is characterized by a difference in renal filtration between cystatin C and creatinine, resulting in a low eGFRcystatinC /eGFRcreatinine -ratio. Studies have demonstrated a high risk for cardiovascular morbidity and mortality for patients with SPS. In this discovery study, we explored associations between SPS and proteins implicated in cardiovascular dis

Genome-wide association meta-analysis identifies pleiotropic risk loci for aerodigestive squamous cell cancers

Squamous cell carcinomas (SqCC) of the aerodigestive tract have similar etiological risk factors. Although genetic risk variants for individual cancers have been identified, an agnostic, genome-wide search for shared genetic susceptibility has not been performed. To identify novel and pleotropic SqCC risk variants, we performed a meta-analysis of GWAS data on lung SqCC (LuSqCC), oro/pharyngeal SqC

Predicting neurological outcome after out-of-hospital cardiac arrest with cumulative information; development and internal validation of an artificial neural network algorithm

Background: Prognostication of neurological outcome in patients who remain comatose after cardiac arrest resuscitation is complex. Clinical variables, as well as biomarkers of brain injury, cardiac injury, and systemic inflammation, all yield some prognostic value. We hypothesised that cumulative information obtained during the first three days of intensive care could produce a reliable model for

Spectroscopic characterization of electronic structures of ultra-thin single crystal La0.7Sr0.3MnO3

We have successfully fabricated high quality single crystalline La0.7Sr0.3MnO3 (LSMO) film in the freestanding form that can be transferred onto silicon wafer and copper mesh support. Using soft x-ray absorption (XAS) and resonant inelastic x-ray scattering (RIXS) spectroscopy in transmission and reflection geometries, we demonstrate that the x-ray emission from Mn 3s-2p core-to-core transition (3

Room temperature multiferroic PZTFT thin films

Multiferroic materials have shown significant potential for next generation nanoelectronic and multifunctional devices due to their coexistent order parameters and versatile tunabilities. Nevertheless, the selectivity of the room temperature multiferroics is extremely limited. In this manner, single-phase solid-solution-type multiferroics that are composed by distinct oxides exhibiting either ferr

Pancreatic cancer is suppressed by fibroblast-derived collagen I

Clinical implementation of anti-stromal therapies in pancreatic cancer has been delayed by unanticipated tumor-restraining properties of the desmoplastic stroma. In confronting these challenges, Chen et al. demonstrate in this issue of Cancer Cell that fibroblast-specific deletion of collagen I, in the background of oncogenic Kras-induced spontaneous murine pancreatic ductal adenocarcinoma, enhanc

The beetle (Coleoptera) fauna of an abandoned exercise field in south Sweden

Species diversity and composition of the Coleoptera (beetle) fauna in a recently abandoned military exercise field in south Sweden was studied during sixteen years. The sixteen square km large area contained deciduous wood (mainly Fagus and Carpinus), shrubland, open ground, and pastures. Beetles were captured using three different methods: pitfall trapping, striking of foliage, and sweep bag coll
